Add a few dllimport/dllexport tests. NFC

Summary:
This change just adds tests for some corner cases of dllimport/dllexport,
primarily for some static methods.

We plan to enable dllimport/dllexport support for the PS4, and these
additional tests are for points we previously were testing internally.
